and exactly where did you get this "Aramaic" as being the "original" language of the New Testament?
It is very common knowledge to anyone who has studied the language of the NT, that the Books were Originally written in Koine Greek.
There are some who argue that some parts/Books of the NT were written in "Aramaic", but with not actual evidence, but conjecture.
The earliest manuscript of the NT, is the Rylands Library Papyrus P52, also know as The St John Fragment. which is written in Greek, and dated as early as around 100 AD.
There are Church Fathers who are of the Greek and Latin Church, who lived in the first and second centuries, who quote the NT in Greek.
The 1st century Church Father, Papias (60-135 AD), is reported to have said, that Matthew wrote down sayings of Jesus in Hebrew. Irenaeus understood this as a reference to Hebraisms in Matthew’s Gospel, whereas Origen took this to mean that Matthew originally wrote his Gospel in Hebrew. So, here it is Origen who made this claim for Papias about the Gospel of Matthew. It is quite possible that some NT Books, or even the complete NT, was translated by some into Hebrew/Aramaic, but there is no manuscript evidence for this.
